The couple met while working on Lavigne's forthcoming fifth album in February, and Kroeger popped the question August 8. "I knew I was falling for her," Kroeger told Hello! Canada of their intense studio sessions. "It was incredibly powerful and something I'll never forget."

According to once-wed Lavigne, Kroeger "makes me laugh every day. He takes care of me in every way and is extremely attentive."

Prior to her relationship with Kroeger, Lavigne dated "The Hills" reality star Brody Jenner, 29, on and off from 2010-2012. She was married to Sum 41 singer and guitarist Deryck Whibley, 32, from 2006-2010. This will be the first marriage for Kroeger.
